PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 788,137, dated April25, 1905.

Application filed May 11,1904. Serial No. 207,450.

To 1/71 'IIILOHL it many con/corn:

Be it known that Lll'inxrni-z H. lrIuxronn, a citizen of the UnitedStates, residing at I'Iuxford, in the county of Hancock and State of)Iississippi, have invented a new and useful Plow-Point, of which thefollowing is a specification.

The invention relates to improvements in plow-points.

The object of the present invention is to improve the construction ofplow-points and to provide a detachable one which will be simple andcomparatively inexpensive in construction and which will possesssubstantially the strength and durability of a solid point.

A further object of the invention is to provide a device of thischaracter which when a plow-point becomes worn will enable the same tobe readily removed and renewed without the services of a skilledmechanic.

\Vith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion, size, and minor details of constructionwithin the scope of the claims may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure I is a perspective view of a plowshare providedwith a point con structed in accordance with this invention. Fig. 2 is areverse plan view. Fig. 3 is a longitudinal sectional view on the line 33 of Fig. 2. Fig. isa detail sectional view on the line i t of Fig. 2.Fig. 5 is a detail perspective view of the plow-point.

Like numerals of reference designate corresponding parts in all thefigures of the d rawings.

l designates a plowshare which is in the form of a sweep; but thedetachable plowpoint 2 is applicable to various center-point plows. Theplowshare is provided at the front with an approximately V-shapedcutaway portion or recess 3, having side edges arranged approximately atright angles to each other to tit the inner or rear edges at of theplow-point 2, which is approximately rectangular, as shown, to providetapered inner and outer portions. The inner tapered portion of theplow-point fits snugly within the recess of the plowshare, and the inneror rear edges abut against the edges of the recess, the upper or outerface of the plow-point being arranged flush with the outer face of theplow share and forming a continuation of the same. The plowshare isprovided at opposite sides of the center of the recess withforwardlyprojecting supporting-flanges 5, which are bent downwardly attheir inner portions to offset their outer or supporting portions fromthe plane of the lower face of the plowshare to permit the plow-point tolie in the same plane as the adjacent portions of the plowshare. Theplow-point is provided at its inner end with a shank or tang 6,extending inward and upward on the lower face of the plowshare, andprovided with a slot 7, through which passes a bolt 8 for securing theplow-point to the plowshare. The shank or tang of the plow-point isarranged between the supporting-flanges of the plowshare, and theplow-point is also provided at the outer side edges of thesupporting-flanges 5 with projecting lugs 9. These lugs 9, which engagethe lower face of the plowshare, are bent downwardly at the rear edgesof the plow-point to offset their outer portions from the plane of theplowshare to enable them to fit snugly against the lower face of thesame. The plow-point is securelyinterlocked with the plowshare by meansof the supportingflanges, the projecting lugs, and the shank or tang,and it may be readily detached by removing the bolt 8 when it isnecessary to renew it. In this manner the plow-point may be readilyrenewed at a little expense and without the assistance of a skilledmechanic. Having thus fully described my invention, what I claim as new,and desire to secure by Letters Patent, is

1. The combination of a plowshare having a recess or cut-away portionand provided at opposite sides of the same withprojectingsupporting-flanges, and a plow-point fitting within the recessor cut-away portion and completing the plowshare and supported in thesame plane as the said plowshare and provided between the flanges with aprojecting shank detachably secured to the plowshare, said plow-pointbeing also provided with lugs engaging the flanges and forming with thesame an interlocking connection between the plow-point and theplowshare.

2. The combination of a plowshare provided with a recess or cut-awayportion and having projecting supporting-flanges at opposite sidesthereof, and a plow-point fitting within the recess or cut-away portionand supported by the flanges and provided between the same with a shankdetachably secured to the plowshare, said plow-point being also providedbeyond the supporting-flanges with projecting lugs fitting against theouter side edges of the flanges and engaging the plowshare, the shank,lugs and flanges forming an interlocking connection between theplow-point and the plowshare.

3. The combination of aplowshare provided with a central tapering recessor cut-away portion and having projecting supporting-flanges at oppositesides thereof, and a plow-point having a tapered inner portion fittingwithin the recess or cut-away portion and provided at a point betweenthe said flanges with a projecting shank detachably secured to theplowshare, said plow-point being also provided with projecting lugsarranged beyond and fitting against the outer side edges of thesupporting-flanges and engaging the lower face of the plowshare, theshank, lugs and flanges forming an interlocking connection between theplow-point and the plowshare.

In testimony that I claim the foregoing as my own I have hereto afiiXedmy signature in the presence of two witnesses.
